Brent catching in Ireland - March 2015

As I write the Dublin-based team, mostly comprising the Exeter researchers led by Stuart Bearhop, are processing a very nice catch of 60+ individual Brent in a week that has seen March go out with a roar! This catch is at Bull Island - thanks to all who are assisting with this catch and of course who spend time without such reward on the days when there are no successes.

As is typical for this time of year the Brent are spending much of their time grazing on the extensive saltmarshes where they are available - Dublin being one site where there are extensive saltmarshes especially around Bull Island. This presents its own challenges as the topography is often tricky for accessing and setting nets and of course, depending on the heights of tides there can be a risk of flooded nets.

Today's catch follows a series of smaller previous catches in Dublin last week, a small catch on inter-tidal habitat at Carlingford Lough and a nice BIG catch (after 2 1/2 days of perseverance ca. 59 birds) at Dundrum in Co. Down (see picture).

Safe to say that Stuart was rather pleased that all the time spent payed off!




As ever there are further updates via twitter feeds (e.g. @StuBearhop) and Facebook links to some of the team.

Dublin: Feb-Mar 2015

Our first major attempt at catching in the Dublin area this year, met with mixed success, although if you had offered me a total haul of 80 birds at the start of the week, I think I would have taken it. We began the recces mid week and as many of the Dublin resighters had already noted, there were a lot less geese around than usual and they were not quite as predictable as they often are.
This seemed to change a bit towards the end of the week and over the weekend, with large flocks regularly out on the grass at Springfield Road, Seagrange Park and Greendale.
However we were also keen to check some of the sites around Rogerstown/Rush as in previous years this had held proportionally large numbers of Canadian-ringed birds and we were hoping to spot some of the birds we had marked during summer 2014. So were excited to see a number of RBs (including at least one family) in the first flock we spotted out on the green next to shore road. Good numbers of birds were joining this flock and it looked like potentially the best place to start thinking about a catch.

We met up with Pat Linders the following morning and after gaining the necessary permissions we were able to set a net. We spent much of the day freezing in the strong SW wind and snow flurries. There were a couple of close passes, but the geese have an uncanny knack for “knowing” almost to the millimeter the catch area of the net and they scuttled around the outside of catch on a couple of occasions (we were also thwarted by dog walkers with luminous jackets and the local Gardai). It was looking like another one of those days as a massive ominous grey cloud loomed in the west, the tide was dropping and all of the birds were now feeding out on the mud flats.

The snow had just started to fall when a small flock of around 40 birds landed back on the green and right in the centre of our catch area. Tom got the firing box ready in record time and we fired almost simultaneously. There were 32 birds to extract as a fairly impressive blizzard hit. We sheltered the birds under a tarp and by the time we had finished the ground was a slushy white colour.
The team comprised: me, Tom, Ian, Freydis and Pat and so we spent the next 3 hours or so furiously processing. The new colour combination for this year is Blue Yellow (see Pat with AABY). We also ran into an old friend from Canada this summer NARB (see pic with Freydis). Finishing just after sunset, all birds flew well into the strong wind on release.

A great start to the week!

The next few days proved much more frustrating. We set at Seagrange Park Tuesday-Thursday and had visits from Graham Mc, the Pats (Watson and Lynders), Niall, Liam, Mark, Ash, Adam, Deirdre and Darren (all three from Trinity), Andrew Kelly and Cian. We had birds close to the catch area on several occasions, but no joy. They were just a bit more jumpy they normal. Indeed on Thursday, we had no birds at all up to 1pm so we lifted and moved up to Kingfisher Green, where they had been pretty reliable all week. It was late in the afternoon by the time we set here, so it was no surprise, when the birds moved off to the estuary, not to return. We returned here on Friday morning setting a full net and a half net to maximise our chances.

Field team processing at Kingfisher Green
Alan Lauder arrived to help with proceedings and we were later joined by: Miryam, Susan, Niall and Cian along with Declan Clarke and a small team from the North (Owen, Miriam and Shanna). We very quickly had birds in catch and were just about to call fire, when a helicopter flew over and sent everything out to the estuary. After about an hour the birds showed no sign of returning and so a couple of us walked out on the saltmarshes to try and move the feeding flocks that had assembled. The birds moved and very obligingly settled on the green, about 200 or so. We tried at first to twinkle them into the half net, but the invisible barrier reared its ugly head again and so we went for the longer approach, with Alan gently pushing them into the wind and towards the full net which was hidden the longer grass at the edge of the green. Within a few minutes we had birds in catch and fired (see a video here: https://www.facebook.com/video.php?v=10153044802275709&l=2910929842652264053). A good catch of 48 birds and only two birds ringed, which will be a surprise to anyone who knows this site. The team were excellent and the last bird went into the keeping cage, just over three hours after we fired, a superb effort from all concerned.

This last catch somewhat saved the week for us, Alan, Tom, Ian and Freydis, tried again on Sunday, but had no luck. So there are 75 new BY ring combinations to be read out there, flying in the face of convention (don’t ask me why) it is the yellows that we have held constant. So there are yellow A, B, C, D & Fs out there if any of the Dublin crew fancies a look. We are heading back over in a couple of weeks, hoping for more success, so if you live in the Dublin area and are reading this please come along or pass your email details to us so that we can keep you posted.

Provisional Results from the November Census...

This is the first time we have tried to conduct a Census of the geese at such a late stage in the Autumn, when we attempted to count as many as possible of our flyway geese on their early wintering grounds. The vast majority of counts came from the weekend of 08 - 09 November 2014.
Whilst figures are still very provisional, and therefore shouldn't be quoted elsewhere, a total of 32,065 brent geese were counted. These were distributed as follows:

Northern Ireland:

Lough Foyle 859
Strangford Lough 17,560
Dundrum Bay 244
Carlingford Lough 124

Republic of Ireland:

Carlingford Lough 7
Dundalk Bay 491
Boyne Estuary 52
Laytown Beach 2
Rogerstwon Estuary 259
Malahide Estuary 342
Baldoyle Bay 69
Dublin Bay 3,288
Kilcoole 3
Wexford Harbour 102
Bannow Bay 186
Ballyteige Bay 33
Tramore Bay 574
Clonea Bay 6
Dungarvan Harbour 700
Castlemaine Harbour 1201
Tralee Bay 3335
Banna Strand 71
Galway Bay 270
Clew Bay 21
The Mullet 217
Killala Bay 352
Ballisodare Bay 234
Sligo Bay 219
Drumcliff Bay 95
Donegal Bay 21
Keadue Strand 25
Braade Strand 52
Ballyness Bay 182
Lough Swilly 100

Scottish Islands:

Islay 26

Scotland:

Loch Ryan 35

England:

Morecambe Bay 80
Dee Estuary 95

Wales:

Anglesey 139
Menai Strait 192

Channel Islands:

Jersey 42

France:

Normandy 160

Overall, the statistics on productivity show that, compared with the total wipe-out disaster last year, productivity and average brood sizes in breeding season 2014 were good, at just over 4% and 2.1 respectively.

Morocco - Now What's That All About??...


An interesting brent goose sighting has come in from Paddy Woodworth from Dublin. He was on holiday at Essaouira, on the Atlantic coast of Morocco, and took the photograph below of a goose he spotted in a pond in coastal dune forest on 02 January 2015:

 
Paddy reported it to eBird, who queried it as extremely unusual, but were happy with his full record and pictures. Subsequently, a guide at Essaouira confirmed to him that brent geese winter just north of the town regularly.
Can anyone add to the current state of knowledge on the southern limits for the species?



Red Letter Day for the Brent Database!!...

With the entry this morning of the 28 December 2014 record from Tramore Backstrand, Co. Waterford, of CURY, with its mate CSRY, from Micheal Cowming, the database has reached the amazing new milestone of over 150,000 re-sightings of marked birds!!
Well done to each of the 986 observers who had been involved in contributing to this figure, with rings read at 1,131 sites and subsites across the flyway. It's no wonder I'm suffering from Repetitive Strain Injury!!

Back on the Move Again, and Apologies...

News has come in this evening that 2IRR, the "Christmas Dinner" bird mentioned in the blog on 30 December 2014, is on the move again, moving up from the Bay of Biscay to Saint-Brieuc Bay in Brittany, where it was recorded today by Anthony Sturbois. It will be interesting to see whether this bird moves back up to the big flocks at Regneville in Normandy.
Secondly, apologies for the lack of input to the blog in recent times, and, indeed, for the very slow rate of feedback some of you will have been experiencing from me recently - I'm currently some three to four weeks behind with data entry. This has been for a variety of reasons, not least the organisation and survey work associated with the International Swan Census, which was held over last weekend. I am hoping to try and catch up somewhat over the next few weeks, so please keep the records coming in!!

Update on Sightings to Date this Winter...

It's a long time since I let you all know how the ring-reading is going this winter, and a mid-season update might be considered worthwhile.
As always seems to be the case by this stage of the winter, I am running well behind with feedback, currently some 3 - 4 weeks, for which apologies to those of you who are waiting. However, please appreciate that there have already been about 6,000 records winging their way to me so far.............!!!!!!!
The position looks as if we are well ahead this winter, but this is somewhat misleading, particularly in the Dublin area, as the intensive ring-reading there by Matt Silk of University of Exeter, as part of his PhD project, had yet to be entered by this time last year. However, I don't think anyone will mind my singling out Christer Persson, who has been out doing his own intensive work as usual this winter across County Dublin, which is mitigating to some extent, our loss of Matt on the ground.
Beyond that, one can see it has been a good winter of ring-reading as birds passed through Strangford Lough, and the overall spread of reporting remains good. And forgive me for saying a special "hi" to all you guys in Normandy - fantastic effort!! Give yourselves a good pat on the back!!
